So, I bought the AH game recently and am reading the cards and now trying to figure out the rules and such. Got the basics down, but now I'm stuck at the finer details.
There are two Mythos cards, that I'm trying to figure out how they work together. There's the first one, 'Happy Days are Here Again, which is of type Environment (Urban). That means it can only get replaced by another Environment card. It states that terror level can not increase when this card is in play.
The next card is The Terrible Experiment, Rumor, which means, as long as it's in play, no other rumors come to full effect. It says: '(blablabla)... Fail: Raise terror level to 10 and put on board a bunch of monsters'
So, I'm curious as to how these two cards actually work together. They obviously can be in play at the same time, as their types are different. Also, if you fail the 'Experiment' card, you will obviously have to stick in 8 monsters. But what happens with the terror level? Does it go up to 10, or does it stay the same? Is there a general rule for incidents like this (or is this a lonely example)?
Can Happy Days be used to 'safely' fail the Experiment event, or does the experiment sort of cancel the happy days card?
